Or use JSON, if your data fits within that structure. It's easy to read and write, it's human-readable, and it's safe (no chance of arbitrary code execution). Forcing yourself to use a format that can basically be processed by ast.literal_eval() is a good discipline - means you don't accidentally save/load too much.
